Description

If you use any SSO method with [BE][cookieSameSite]="lax", the backend will give an error:

Blocked a frame with origin "https://domain.tld" from accessing a cross-origin frame.

It's because file /typo3/sysext/backend/Resources/Public/JavaScript/ContextHelp.js uses "use strict".

Solution:
ContextHelp.js must take over the value of setting [BE][cookieSameSite]

Can you please elaborate on why use strict causes this behavior? use strict enables JavaScript's strict mode regarding error handling and code execution, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode.
